Specification of Letters Patent.

Patented April 23, eo'z.

Application filed August 5, 1904. Serial N 0. 219,624:-

To all whom it may concern.-

Be it known'that I, HARRY F. BUSHONG, a citizen of the United States, residing at the city of .Kalamazoo, county of Kalamazoo, State of Michigan, have invented certain new and useful improvements in Temporary Binders or Loose-Sheet Holders, of which the following is a specification.

This invention relates to improvements in temporary binders or loose sheet holders.

The objects of this invention are: F irst, to provide an improved temporary binder or loose sheet holder adapted to securely retain any numberof sheets or leaves, from one to its maximum capacity. Second, to provide an improved temporary binder or loose sheet holder in which any particular sheet or leaf may be quickly released or removed, or a new sheetor leaf inserted without disturbing the other sheets or leaves. Third, to provide an improved temporary binder or loose sheet holder which is adapted to open flat and to hold the sheets or leaves so that they lie flat, or substantially flat, when the book is opened for use. Fourth, to provide an improved temporary hinder or loose sheet holder in which the securing devices are so arranged that the strain thereon and upon the leaves in using the book is reduced to a minimum. Fifth, to provide an improved.

temporary binder or loose sheet holder in which the adjustment for the maximum or minimum number of leaves or for any inter:

mediate number of leaves does not affect its finished and. complete appearance. Sixth,

to provide an improved temporary binder or loose sheet holder in which the adjustment of the back strip or piece is controlled by the adjustment of the clamping devices for the leaves or sheets. Seventh, to provide, in a temporary binder or loose sheet holder, an improved sheet clampingor retaining means.

Further objects and objects relating to structural details will definitely appear from the detailed description to follow.

I accomplish the objects of myinvention by the devices and means described in the following specification.

The inventionis clearly defined and pointed out in the claims.

A structure embodying the features of my a part of this dinal sectional View of my improved temporary binder or loose sheet holder in itsclosed position, taken on a line corresponding to line 2 2 of Fig. 1, the adjusting screw shaft D being shown in full lines. Fig. '3 is a detail longitudinal sectional view showing the arrangement of the sheet or leaf clamping means. Fig. dis a transverse sectional view taken on a line corresponding to line 44 of Fig. 2, showing further details of the clamping means for the sheets or 'leaves. Fig. 5 is an enlarged detail transverse sectional view taken on a line corresponding to line 5 5 of Fig. 2, showing the structural details of the covers. I view through one of the covers, showing the structural details thereof. Fig. 7 is a detail plan view of one of the sheets Ffshowing the e hole shaped slot f therein. 7

- n the drawings the sectional views are taken looking in the direction of the little arrows at the ends of the section lines, and similar letters of. reference refer to similar parts throughout the several views.

Referring to the drawings, the covers are made up of rectangular frames consisting of side pieces A and end pieces A A. These frame pieces are preferably of wood. The inner walls B of the covers are made of sheet metal and are provided with rearwardly and inwardly turned flanges b-at 'each side, which embrace the side pieces A of the frame. The flanges of the walls are provided with project ing hinge pieces I) at their inner ends. (See Fig. 6.) Finishing strips B, preferabl of wood, are secured to the outer faces of t ese flanges b. The outer Walls B of the covers are secured upon the flanges b. lam thus enabled to secure covers having a chamber therein, which are light and strong and of moderate thickness.

Fig. 6 is a longitudinal sectional A pair of clamping bars 0 are pivotally secured to the hinge pieces I) of the covers 'sembling. i

erablyflat on their inner or clamping faces and are preferably rounded on their rear or outer faces so that they may rock on their journals without engaging the inner edges of the covers. (See Fig, 2 and 3.) The clamping bars C are provided with pairs of transverse perforations c therethrough to receive the binding thongs or cords D which are arrangeddinally arranged threaded shaft Dwhich is supported insuitable bearings (1 within the cover. This shaft is controlled by a suitable key, as (1. (See Fig. 1.) The binding cords D are preferably formed of a single piece which is looped around the block a. This block a is preferably curved so that the hinding'cord is free to adjust itself over. it, thereby maintaining an equal tension thereon and upon the clamping bars throughout their length. In loosening the clamping bars for the insertion of leaves,'the binding cord passes or slides back into the chamber in the cover, as indicated by the dotted lines in Fig. 1, which prevents any knotting or twisting thereof. However, the structure is quite satisfactor with the binding cords independently and rigidly secured, instead ofbeing connected and secured as illustrated in Fig. 1.

A back piece or strip E, adapted-to telescope in the chambers in the covers, is provided. This back-piece is secured by tapes 6 to the adjusting bar D of the binding cords. (See Fig. 1.) The other end of the back-' strip-is secured by the tapes e to the frame of theopposite cover. These tapes e e. are preferably' elastic, as this avoids the necessity for accurate adjustment'of the parts in es- With the parts thus connected, whenthe clamping bars are adjusted, the back piece or' strip is alsoadjusted so thatit is automatic ally drawn out or telescoped'within' the covers, always presenting anat'tractive and finished' appearance.

Any number ofle'aves or sheets, from one to the maximum number, are securel res tained by my improved'loose' sheet ibin er'or holder. 7

My improved 'Binder is adapted a open flat, and at the same time-the leaves or sheets are so held that they lie lfiat ior'practi cally, sowhen open for use,and the-strain u on the binder and" upon the leayes is reduce to a minimum. Theleaves are'clam edalon their entire rear edge so that; the angero their being torn is reduced to amim'mum;

Thus arranged, the covers may are so held that there is no liability of their becoming detached'fro'm-the clamping bars when loosened for the purpose of removing or inserting leaves. 4

I have illustrated and described my im roved' temporary hinder or loose sheet holder in the form preferred by me on ac. count of 'its structural simplicity and the economy with which the parts may be produced and assembled. I am, however, aware that it is capable of very great structural variation without departing from my invention.
